Wormhole dynamics in FRW universe.
Abstract
The possibility of the formation of the wormhole structure in the era of inflation is investigated by applying the thin shell formalism. At the late stage of the old inflation model, some parts of the false vacuum region may be surrounded by the true vacuum bubbles. In such a situation, the formation of the untraversible wormholes may be possible. The authors present a more realistic description of the global structure of spacetime stated above than in the original work. They study the traversable wormhole dynamics in Friedmann-Robertson-Walker universe. Contrary to the Morris-Thorne wormholes, it can be possible to make a spacetime which contains traversable wormholes which satisfy weak energy condition everywhere.
